No input multiplexer, no inter-channel phase delay. That makes this part a direct fit for polyphase energy metering, protective relay current/voltage sensing, and multi-axis vibration monitoring where you need time-coherent data across every channel. Each channel includes a PGA ahead of the modulator. The reference can be internal or external, and the digital interface is SPI. The package is a 32-pin WFQFN with exposed pad (4 mm × 4 mm QFN), surface-mount only. ## 24 bits at 32 kSPS — what the sampling rate and resolution mean for your measurement chain The 24-bit sigma-delta modulator provides 24-bit resolution. The 32 kSPS per channel captures harmonic content in power-quality analysis. Because all eight ADCs run simultaneously, you get true simultaneous sampling — no skew from a round-robin mux. This is essential for calculating per-phase real and reactive power in a three-phase system where voltage and current samples must align in time. ## Package and tape options — what ships on the reel","metaTitle":"ADS131M08IRSNR 24-bit 8-channel Sigma-Delta ADC, 32 kSPS","metaDescription":"TI ADS131M08IRSNR 24-bit 8-channel simultaneous-sampling sigma-delta ADC with PGA, SPI, -40 to 125°C.
